PROLOG
       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME
       posix_spawnattr_getpgroup, posix_spawnattr_setpgroup - get and set the spawn-pgroup attribute of a spawn attributes object (ADVANCED  REAL-
       TIME)

SYNOPSIS
       #include <spawn.h>

       int posix_spawnattr_getpgroup(const posix_spawnattr_t *restrict attr,
	      pid_t *restrict pgroup);
       int posix_spawnattr_setpgroup(posix_spawnattr_t *attr, pid_t pgroup);

DESCRIPTION
       The  posix_spawnattr_getpgroup()  function  shall  obtain  the value of the spawn-pgroup attribute from the attributes object referenced by
       attr.

       The posix_spawnattr_setpgroup() function shall set the spawn-pgroup attribute in an initialized attributes object referenced by attr.

       The spawn-pgroup attribute represents the process group to be joined by the new process image in a spawn  operation  (if  POSIX_SPAWN_SETP-
       GROUP is set in the spawn-flags attribute).  The default value of this attribute shall be zero.

RETURN VALUE
       Upon  successful  completion,  posix_spawnattr_getpgroup() shall return zero and store the value of the spawn-pgroup attribute of attr into
       the object referenced by the pgroup parameter; otherwise, an error number shall be returned to indicate the error.

       Upon successful completion, posix_spawnattr_setpgroup() shall return zero; otherwise, an error number shall be  returned  to  indicate  the
       error.

ERRORS
       These functions may fail if:

       EINVAL The value specified by attr is invalid.

       The posix_spawnattr_setpgroup() function may fail if:

       EINVAL The value of the attribute being set is not valid.

       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       These functions are part of the Spawn option and need not be provided on all implementations.

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
